Intelligent. Intuitive. Ingeniously Practical.The OHAUS Explorer® Series has risen to the next level of ingenuity—expanding on its modern features and design to offer unmatched functionality in a line of high-performance balances unlike any other on the market.
Standard Features Include: Intelligent PERFORMANCE—All Explorers have newly optimized linearity and repeatability specifications and enhanced vibration filtering for better balance stability. All models also come standard with AutoCal™ automatic internal calibration. 3×3 filtering setup ensures fast and stable weighing results. The Explorer EX…/E models additionally offer traditional external calibration. These combined enhancements improve accuracy, efficiency, and throughput.
Intuitive OPERATION—A large color touch-screen display, icon-driven application software that features 14 unique application modes, and a 3 level adjustable angle display make Explorer the easiest to use, most advanced balance in its class today.
Ingenious DESIGN—The base and display separate for maximum flexibility in any work area. Draftshield models isolate the weighing chamber to enhance stability and speed results while offering maximum accessibility to the weighing chamber through top-mounted side doors or through the versatile top door that flips or slides open. Hands-free entry is available with optional automated side doors.
Practical Features—Explorer has up to four user-programmable touchless sensors to minimize cross contamination and wear and tear normally associated with repeated touching of the balance. The OHAUS Explorer EX...N series of balances meet or exceed the Class I or II accuracy requirements in accordance with NIST Handbook 44 and Canada’s Weights and Measures Regulations.

Ingenious DRAFTSHIELDExplorer’s draftshield provides ample access and visibility to the weighing chamber through the versatile top door and side sliding doors. Select models feature motorized side doors that open and close automatically with use of the touchless sensors on the base and display.
The automatic draftshield door models have a new function for auto-matically opening draftshield doors without touching the balance. It helps to eliminate sample residue transfer and contaminations.
Side doors seamlessly glide on top-mounted bearings
The versatile top door offers two entry options; access the weighing chamber by flipping the top door or sliding the glass panel open.
The expansive side entry 6.3” × 9.4” (160 mm × 240 mm) allows you to freely place and remove large weigh boats or other large vessels in the weighing chamber
Antistatic coated glass helps dissipate static charges in the weighing chamber which could adversely affect the weighing results
Easy to install and remove glass panels and a stainless steel bottom make Explorer extremely easy to clean
A draftshield chamber light is available when the balance is used in low lighting environments
Practical TOUCHLESS SENSORSExplorer features up to four touchless sensors for hands-free operation of zero, print, calibration, tare, automated draftshield doors and other selectable functions
Hands-free operation —Improves weighing efficiency —Eliminates sample residue transfer —Minimizes contamination
Two sensors on the base* and two on the display can be set up individually to allow for remote operations
The sensors can be set up to provide automated operation of the draftshield side doors and can be programmed to automatically open the opposite side door in order to support efficient and logical sample placement with your free hand.
* Analytical and precision models only. Automatic Draftshield door operation only offered on Analytical models
Explorer® Analytical, Precision, High CapacityIntelligent CALIBRATIONAutoCal™ ensures performance and assists with routine maintenance by automatically calibrating the balance daily.
Self-calibrates the system when it senses a temperature change sufficient enough to affect weighing accuracy, or every 11 hours
Performs routine calibration and reduces the need for external masses
External Calibration Models Available — Select models feature traditional external calibration in which external weights (user’s choice of calibration weight values) are required to calibrate the balance to ensure accuracy
Intuitive USER SETUPExplorer is the industry’s most easy-to-use balance, featuring leveling assistance and instructional messaging for quick out-of-the-box setup and use.
Easy to view illuminated level indicator placed at the front of the balance
Adjustable thumbwheels are easy to turn to level the balance
Level assist screen helps users quickly identify which thumbwheels need to be adjusted to level the balance
Data Transfer Function helps to output data directly into Microsoft Excel
Instructional messaging during application use guides users through the weighing process
User information menu allows users quickly view and learn more about the available balances features
Up to 13 operating languages make Explorer’s Intuitive User Setup truly universal
